> (Security) Oozie style delegation tokens for HDFS/HBase
> -------------------------------------------------------
>
> Key: STORM-346
> URL: https://issues.apache.org/jira/browse/STORM-346
> Project: Apache Storm (Incubating)
> Issue Type: Bug
> Reporter: Robert Joseph Evans
> Assignee: Parth Brahmbhatt
> Labels: security
>
> Oozie has the ability to fetch delegation tokens on behalf of other users by
> running as a super user that can become a proxy user for almost anyone else.
> We should build one or more classes similar to AutoTGT that can fetch a
> delegation token for HDFS/HBase, renew the token if needed, and then once the
> token is about to permanently expire fetch a new one.
> According to some people I have talked with HBase may need to have a JIRA
> filed against it so that it can pick up a new delegation token without
> needing to restart the process.
